CARRIER BLOCK FOR LUMBER CARRIERS.

Application filed. February 10, 1927. Serial No. 167,296.

This invention relates to carrier blocks for lumber carriers and has foran important object thereof the provision of a device of this characterwhich will increase the amount of lumber which may be carried by thecarrier.

A further object of the invention is to produce a device of thischaracter so constructed that the lumber will be very firmly held inposition thereon and there will not be thetendency of the lumber to slipwhen the load is lifted or dropped by the carrier that there is with theordinary structure.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure l is asectional View through a lumber carrier having carrying blocksconstructed in accordance with my invention;

Figure 2 is a section on the line 22' of Figure 1;

Figure 3 is a longitudinal sectional view through the carrying block;

Figure 4 is a section on the line M of Figure 3.

Referring now more particularly to the drawings, the numeral generallyindicates the carrying rails of a lumber carrier, which are verticallyadjustable to enable the load to be elevated from and deposited upon theground. These carryingrails have inwardly directed flanges 11 which areengaged beneath cross bars which in turn support the lumber. Inaccordance with my invention, I provide a cross bar 12, preferably inthe form of an inverted channel having castings 13 secured to the endsthereof and provided with vertically offset flanges 14 adapted to restupon the flanges 11 of the carrying rails. While the offset portions arepreferably provided by castings above referred to, these offsets may beproduced upon the ends of the bar 12 in any suitable manner. The undersurface of the flange 14: is preferably provided with a socket 155, forthe reception of a rubber pad 16, which actually engages the carryingrails and increases the grip of the flanges 14 thereon.

In the preferred construction herein illustrated, the arms 17 of thechannel section 12 diverge downwardly. The base or channel engagingportion 18 of the casting 13 is provided in its upper surface with adepression 19, preferably of slightly greater depth than the thicknessof the base portion 20 of the channel member and upon whlch this baseportion seats. Downwardly diverging channel arm receiving grooves 21 areformed in this base section into which the channel arms may be slid byan endwise movement of the channel member. Securing elements 22 directedthrough the base section of the channel member into the base section ofthe casting serve to prevent separation thereof.

It will be obvious that since the depression 19 is made of slightlygreater depth than the thickness of the base 20 of the channel, the ribs23 produced by the channel receiving grooves will extend slightly abovethe upper surface of the channel member and will, therefore, serve tohold against dislodgment a facing strip 24, which may be of wood orother suitable material upon which the lumber to be carried will seatmore firmly than it ordinarily will upon a metal surface. It will beobvious that by vertically offsetting the ends of the bar, the carryingcapacity of the carrier will. be increased and that furthermore lumbercannot be knocked out of position with relation to the bar by a blowagainst the side thereof. In this connection, it is pointed out that inmanipulating the lumber carrier into position over the load, the sidemembers 25 from which the carrying rails 11 are supported, often come incontact with the lumber and with the present structure tends todisarrange the same sufiiciently to require re-loading thereof.

It will be obvious that a device of this character may be very cheaplyand readily produced and will materially facilitate the loading of thecarrier and increase the efficiency thereof. It will furthermore beobvious that certain changes can be made in the structure hereinbeforeset forth without in any manner departing from the spirit of theinvention and I accordingly do not limit myself to such specificstructure except as hereinafter claimed.

Iclaim:

1. A carrying bar for use with lumber carriers comprising an invertedchannel bar and a pair of castings each having in its upper surface asocket for the reception of the base portion of the channel and beingfurther provided with grooves receiving the ends of, the arms of thechannel, said castings each including a vertically offset out- Wardlydirected flange adapted to engage the carrying rail of the lumbercarrier.

2. A carrying bar for use with lumber carriers comprising an invertedchannel bar and a pair of castings each having in its upper surface asocket for the reception of the base portion of the channel and beingfurther provided With grooves receiving the ends of the arms of thechannel said castings each including a vertically offset out- Wardlydirected flange adapted to engage the carrying rail of the lumbercarrier, the sockets of said castings being of greater depth than thethickness of the base of the channel bar whereby the castings and theupper surface of the channel bar combine to form sockets for thereception of the ends of a strip of anti-friction material applied tothe upper surface of the bar.

In testimony whereof I hereunto aflixmy 20 slgnature.

ANTONE GARMO.
